More new commercial vehicles were sold last month than ever before, as sales continued accelerating.

A total of 4002 new commercial vehicles were registered in June, the strongest month for commercial-vehicle sales on Motor Industry Association (MIA) records.

The sales were 26 per cent higher than the same month last year, as Toyota raced away with more than 1100 commercial vehicle sales during the month.

MIA chief executive David Crawford said the commercial vehicle figures for June were "phenomenal".

"Not only being the strongest June sales since the MIA began collecting records for commercial vehicles in 1981, ... [it was] the strongest month of any monthly commercial sales," he said.

Overall, 12,519 new vehicles were sold during June.

New passenger vehicle sales were 13 per cent higher than the same month last year and 11 per cent ahead for the year to date.

"The strong New Zealand dollar, competitive pricing and New Zealanders' confidence that the economy is heading in the right direction have all combined to help drive sales of new vehicles skywards as records continue to fall," Crawford said.

Toyota was the passenger car market leader for the month of June with 17 per cent share (1448 units), with Holden second on 960 units and Hyundai a close third also with 940 units. Toyota also led commercial vehicle market with 28 per cent, selling 1107, followed by Ford on 647 units and Holden 384.

It was a Toyota trifecta at the top of the passenger model with the RAV4 leading with 371 sold, followed by the Corolla 333 and the Highlander 308.

The Toyota Hilux was the top selling commercial model for June with 847 sold with the Ford Ranger next with 574 and the Holden Colarado 359.

As a result, Hilux has regained the lead as the top selling commercial model with 2915 sold, ahead of the Ranger's 2757.
